Li-ion/Li-Polymer Battery Charger

Accepting Two Power Sources

The ISL6299A is a fully integrated low-cost single-cell Li-ion

or Li-polymer battery charger. The charger accepts two

power inputs, normally one from a USB (Universal Serial

Bus) port and the other from a desktop cradle. The

ISL6299A is an ideal charger for smart handheld devices

that need to communicate with a personal computer via

USB.

The ISL6299A features 28V and 7V maximum voltages for

the cradle and the USB inputs respectively. Due to the 28V

rating for the cradle input, low-cost, large output tolerance

adapters can be used safely. When both inputs are powered,

the cradle input is used to charge the battery. The charge

current is programmable for the cradle input with a small

resistor. The end-of-charge current for the cradle input is

also programmable by another external resistor. The charger

incorporates Thermaguard™ which protects the IC against

over temperature. If the die temperature rises above a

typical value of 100°C, a thermal foldback function reduces

the charge current automatically to prevent further

temperature rise. The charger preconditions the battery with

low current when the battery voltage is below 2.6V. The

charger has two indication pins. The PPR (power present)

pin outputs an open-drain logic LOW when either the cradle

or the USB input power is attached. The CHG (charge) pin is

also an open-drain output that indicates a logic LOW when

the charge current is above a minimum current level. When

the charge current is below the minimum current, the CHG

pin indicates a logic HIGH signal and the status is latched.

The latch will be reset at one of these events: (1) the part is

disabled and re-enabled; (2) the selected input source has

been removed and re-applied, (3) The USBON turns LOW,

or (4) The BAT pin voltage falls below the recharge threshold

(~4.0V).

Ordering Information

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
